T4 diameter of 12.7 mm

4. What do “cool white” and “warm white” mean, and what is CCT of LED tubes?
The Color Correlated Temperature (CCT) is given in the description of each of our LED tubes. The color (CCT) of our LED tubes ranges from a warm yellow white (2700K) to a cool blue white (7500K).

6. Are white LED tubes dimmable?
Dimming LED tubes depends on the design of the product, Since LED tubes are current driven devices, and it is not advisable to lower the voltage in order to dim a tube. Dimming does not lower the lamp life of the LED tubes and can often increase it.

7. Q: Do LED Tubes contain hazardous chemicals?
A: LED tubes contain no hazardous chemicals. It is a little-known fact that many Fluorescent tubes contain Mercury and Phosphor. If a tube is broken, the potential for poisoning exists, especially if proper clean up procedures are not followed. Because of the relatively short life of fluorescent tubes, their collective impact on the environment can be significant.

4. Q: Do LED Tubes flicker or emit ultra violet?
A: LED Tubes do not flicker. The light emitted by an LED tube is very stable and produces no side effects. The “color” of LED tubes is 5000K to 6000K.
LED tubes do not emit ultraviolet. The level of UV emitted by most fluorescent tubes is so low as to be irrelevant. Tests indicate that 8 hours of exposure to the UV light emitted by a fluorescent tube is the equivalent to two minutes of midday sun.

Environmental Safety of LED Tube Lighting

Nowadays, more and more consumers buy LED tube lighting, and they are unhappy with fluorescent bulbs, because of their tendency to flicker when being powered on and at the end of their life span, there are environmental issues that also enter into the equation. The reason they are so bad for the environment is that they contain mercury. Scientists have been aware of this for years, but it is doubtful that anyone anticipated quite the impact having millions of mercury containing bulbs in the world, could pose to the environment.

Does LED tube lighting flicker? Yes, they do flicker, but at a rate that is so fast, the human eye is unable to detect it. However, there is LED tube lighting that is manufactured to flicker or aesthetic reasons, and not through any manufacturing defect. Fluorescent lights are known to flicker annoyingly, yet that is the least of the dangers they pose. Toxic metals pose a far greater threat in fluorescent bulbs. Neither LED tube lighting flicker nor contain hazardous substances. In both respects, they are the better.

Therefore, LED tube lighting is now built with filters that help even out the amount of electrical current that are being generated to them. The effect is a flicker that is so steady and so fast that it cannot be detected with the naked eye. Before being installed, LED tube lighting was known to flicker a little bit with each fluctuation of electric current they received. Nowadays, LED tube lighting is as reliable as any other form of light bulb, and is far better for the environment.

Are LED Tube Lamps Proper Replacements for Conventional Lights?

Generally speaking, LED tube lamps are proper replacements for conventional lights, because brightness is an important factor, as we previously mentioned. According to a relevant survey, the brightness of LED tube lamps can reach up to replacement specifications.

Firstly, in terms of color rendering, the CRI of LED lighting is not as high as that of conventional lights. While LED products from the major brands do not match conventional lights in terms of CRI, they still meet various national standards.

Secondly, the beam angle is another important standard. Looking at things from conventional lights standpoint, most LED products are not up to par as the light distribution of conventional lights is general and non-directional. As LED tube lamps are inherently directional, a different standard is required for measuring LED beam angle. The lifespan of a single incandescent bulb is 1,000 hours. However, the lifespan of LED tube lamps can reach up to 50,000 hours. Looking at it from a different angle, the lifespan of a single LED tube lamp is equal to that of twenty-five conventional lights.

While many manufacturers claim that their LED tube lamps are proper substitutes for conventional lights. Actually, there are few products that meet replacement standards. With the development of the LED technology, LED tube lamps still come out on top in regards to cost-performance ratio.

How to Choose the Dimmable LED Tube

Dimmable LED tube has recently become among the leaders in sustainable, energy-efficient, sturdy lighting. As technology has superior, its application has expanded from flashlights to contain interior lighting, landscape lighting and more.

Dimmable LED Tube

In order to meet customer demand, you’ll be able to now purchase dimmable LED tube within the same styles that you simply can buy you a lot more standard incandescent bulbs, which means which you do not must handle the unsightliness of numerous compact fluorescent light bulbs. Whilst you might not need an electrician to trade out your old bulbs with more efficient LED tubes, you could wish to get in touch if you want to install new lights or fixtures.

The greatest advantage of dimmable LED tube will be the reality that they’ve a much extended lifespan and reduced power consumption. To be able to correctly understand this, we must examine LEDs against other light bulb technologies. An incandescent bulb, for instance, will normally last for all around 1,000 hrs. A compact fluorescent bulb can final for about 8,000 hours. An LED bulb, alternatively, will function for up to 50,000 hours. This can be a very significant boost above the two incandescent and compact fluorescent technologies. Dimmable LED tube lights are also free of mercury, which is now a point of contention relating to CFLs.

Furthermore to lasting longer, dimmable LED tube lights are also a lot a lot more effective than other light bulb technologies. Due to this, they give off much less heat and consume significantly much less power than other lights. Consequently, there are numerous applications, which you are able to discuss with a neighborhood electrician, which are perfect for dimmable LED tube.

Advantages of Using LED Tube Lights

1, Low power consumption and long life time
The lifetime of LED tube lights is usually 10 to 15 years which is three times the life of current technologies adopted. The LED’s also have low maintenance cost which brings more benefits to you.

2, High color rendering
The color rendering index is the ability of a light source to correctly reproduce the colors of the objects in comparison to the normal light source.

3, Time-saving
Unlike flourescent bulbs which take time to heat up once switched on LED tube lights turn on instantly. LED’s don’t have problem with hot ignition

4, RoHS complaint free
LED tube lights do not contain Hg/Pb and do not emit poisonous gases

5, Less attraction to nocturnal insects
Insects are sensitive to the UV-blue and green region of the light spectrum. Nocturnal insects are attracted to the emission of UV-blue and green light from conventional light sources. White LED tube lights, however, emit light in a small peak in the blue range and smaller in the green range, so nocturnal insects are less attracted to such light sources.

6, Easy to design non glare lighting equipment
Most LED tube lights are designed to cast its light in a rectangular pattern, compared to traditional lights, which typically have a reflector on the back side of a high-pressure sodium lamp. In this case much of the luminance of the light is lost and produces light pollution in the air and surrounding environment.

A Brief History of LED Tube

To fully understand why are LED tube lights so beneficial, we need to know about the history of lighting. From everything to the home lights and large commercial lighting, we see new innovations regularly in the marketplace. LED tube is important to our modern way of life and we also depend on it for safety. Because of this, LED tube lighting has changed a lot over time and the types of lighting we now have today in our modern times are different than those of the past. With LED technology development, we see more advanced technologies of our lighting but it’s all based on those simple beginnings.

LED tube light

Early sources of light included fire and lanterns and then less primitive methods were created that more closely resembled what we are used to today. People did not have electricity in their homes and businesses like we do today. New strides have been made in the industry to create LED tube lighting that is more energy efficient.

LED tube lighting came along as a great alternative to indoor lighting for many people. We saw them in offices, in kitchens, in bathrooms and more. But as times continued to change and technology advanced, we see even better lighting. Now UL LED tube lights have replaced incandescent and fluorescent lights in most places.
